Then that's the route I'd go on the furnace (natural gas) as its by far the cheapest option. If you are using ~4,000kWh a month and your bill is only $300, then you are paying less than $0.10/kWh, which is quite cheap. If it goes up just to $0.10/kWh, that becomes $400.00, plus delivery and all the other fun charges. Up here that would be $520 in electricity alone, perhaps even more, and then delivery, regulatory and tax, you'd be close to a grand. Even at what you are paying presently, it really wouldn't take that long with bills at that level for you to recoup the cost of a gas furnace. Is your regular water heater also electric? might make sense to convert that at the same time if you can strike up a deal with the HVAC folks that saves you money on both.
